The weather may be dull but spectators and players at the Irish Open will be donning some of their most colourful clothing today.

Forget sartorial formality and fuss - Wacky Trousers’ Day is back and the Dubai Duty Free Irish Open hosted by the Rory Foundation is anticipating a parade ring of the most unique and unusual golfing attire from players and fans alike.

Organisers have invited all spectators - young and old - to don their most flamboyant, fun, or outright outrageous outfits today.

The prize for wearing the wackiest trouses is a €500 voucher with award-winning Emirates airline.

European Tour Championship Director of the Dubai Duty Free Irish Open, Antonia Beggs said: “In terms of inspiration, spectators have no end of golfing role models from whom to choose and the judges will be looking out for lots of colour, eccentric style and eye-catching apparel.

“Our wacky trouser fashion spotters will be keeping an eye out for a worthy group of finalists, who will be invited to attend a finals parade.

“Think Cheltenham or The Galway Races – only wackier and much more fun.”

This year’s tournament is playing host to a field featuring some of the world’s leading golfers including Rory McIlroy, Graeme McDowell, Padraig Harrington, Darren Clarke, Ernie Els, Sergio Garcia, Lee Westwood, Rickie Fowler, Luke Donald, Patrick Reed and Martin Kaymer.
